what size cxr intercooler do you guys run on your stock turbo?

 

honeslty as much as ppl say to big an intercooler will hurt performance thats not to true lol... the average person will not notice the difference in spool up...

as a rule of thumb just go wit the biggest intercooler u can fit with out hindering flow to the radiator.... but dont be dumb lol.. u dont honeslty need a 5 row intercooler wit 3.5in piping...

 

well im thinking about buying this

its going on a 2.2 with the lnf turbo

 

heck man i bought ebay piping and modded it to fit my blitz core..... honestly an ebay pipe kit aint bad.. heck even the coolers arnt bad... its just the end tanks dont flow aswell as a mad tyte JDM unit lol


but for an average build the ebay core isnt bad.... might cost u like 5 whp lol if that...

 

ok good as long as i stay under 250 im good. im not ready for rods and pistons just yet. do you by any chance know how long of one i need to fill up the ss/tc lower grill?

 

To big of an intercooler is worthless. More pressure drop and more lag. Get one sized to your horsepower goals. I know a good real cheap brand. hold on

 

heck just get a basic 2 row maybe 3 row cooler off ebay and ull be fine....

 

i was going with cxr since i heard they are the best bang for the buck. and really cheap. its Overall Size: 29x11x3 inch with 2.5 piping seems sufficient to me. but then again i have been known to be wrong.

Those are list prices. A shop who supplies Yonaka can get them for about half of list or less. Had one on my 240. It cost like $150. Super high quality and they're a bar and plate design.

 

that dont sound bad.... should be perfect for u...

That would probably support your build perfectly.

Supports 350 hp and leak tested to 30 psi.

 

does it come with brackets? i liked how the cxr could be bolted to the bottom of the crash bar. thanks for the link. now where can i get it cheaper?

 

I got the s-max "tuner" intercooler and few other ppl on this forum and other forums have the "tuner" IC as well, from testing it and design it - it's the best bang for your buck.. there FMIC is awesome for street or strip.. it's tunable..

it has a high flow rate design for no boost or lag.. turbo spools 10% faster = 10% to 14% increase in HP and TQ..

i've helped them out with designing the FMIC for the Cobalt, HHR and Ion..

Here is a link to the testing results we've done..

The difference in lag between a stock setup and someone running 3.5 inch charge pipes and a huge intercooler is basically nill. Do you realize how much air a turbo can move? It may take 1/10 of a second longer to fill it if that.

 

^^^^^^^^^^^ speaks the truth......

 

no pricing on the s max. no offence but the tuner isnt for me. it looks nice and all but i dd my car

 

I may get bashed for this, but Crazy Steve's Intercooler is also a great price and is a direct bolt on for cobalts.

i like the crazy steve. kinda spendy but looks good. i have also thought about an oem one too. but those are $244 new and people want almost that much for used. im taking measurements today so i know what size i want. i want to bolt it to the bottom of the crash bar and it fill up most of the lower grill if not all. then i got the hard part done besides finding the stupid manifold for the lnf

 

Are you just doing a full LNF conversion or what?

That's what I would do. I mean there are a ton of SS Cobalts with intercoolers and stock piping sitting around. manifold will be tough.

 

exhaust manifold bolts right up. people say i cant use the stock piping though. most people want $200 for their stock intercooler. which is nuts imo. i wish i could find one local and take the parts i need.
